Medications like semaglutide (Wegovy®, Ozempic®) and tirzepatide (Zepbound®, Mounjaro®) have published prescribing criteria. This checks your numbers against those criteria in about 30 seconds — so you walk into your appointment already knowing where you stand.

How you compare to the criteria
What the prescribing criteria actually are
GLP-1 medications approved for chronic weight management are generally indicated for adults with:
- A BMI of 30 or above (obesity); or
- A BMI of 27 or above (overweight) plus at least one weight-related health condition — such as high blood pressure, type 2 diabetes, high cholesterol, obstructive sleep apnea, or cardiovascular disease.
Meeting the criteria is not the same as being prescribed the medication. A clinician also reviews your medical history, current medications, labs and personal goals — and insurance coverage is a separate question again. Some people who meet the criteria shouldn’t take a GLP-1; some who don’t meet them have better options available.
These medications carry a boxed warning regarding thyroid C-cell tumours and are not for people with a personal or family history of medullary thyroid carcinoma or MEN 2. They are also not recommended in pregnancy.
If you don’t meet the criteria — what else works
A GLP-1 is one tool, not the only one. ThinfastMD has treated weight medically since 1984, well before these medications existed:
- Prescription appetite suppressants — phentermine and related medications, prescribed and monitored by a physician.
- OPTIFAST®-based meal replacement — a structured, medically monitored programme with published clinical results.
- Dietitian-led nutrition and behaviour support — the part that determines whether weight stays off, with or without medication.
The right combination depends on your history, not just your BMI.
Educational tool — not medical advice, a diagnosis, or a prescription. This checker compares numbers you enter against publicly published criteria. It cannot account for your medical history, medications, or labs, and it does not guarantee that any treatment is appropriate, available, or covered by your insurance. Only a licensed clinician who has evaluated you can make that call.
